Human chorionic gonadotropin to oocyte retrieval interval in in vitro fertilization--how critical is it ?
This study shows that modification of the hCG-oocyte retrieval interval from 34 1/2 hours to 37 hours in patients having IVF had no significant effect on the number or quality of oocytes retrieved or on the ultimate pregnancy rate. More consideration can therefore be given to other factors such as patient convenience when scheduling the timing of hCG administration.
